Problems solved by technology

Theoretically, these steps add additional risks for re-introducing bacteria to the injection site in many ways.
These simple steps also add multiple supplies to the procedure, with each item potentially increasing the risk of contamination.
The technical maneuvers of a subconjuctival injection can often require awkward positioning and risks needle contact with potentially unsterile lids and lashes, which may then contaminate the subconjuctival space.
Conventional procedures employing separate aqueous antiseptic and anesthetic agent applications are limited in their effectiveness as most of the liquid is lost due to run-off due to the contour of the eye and eyelids, thereby limiting the beneficial amount of contact time between agents and the ocular surfaces.

Abstract

The present invention comprises compositions and methods for contemporaneously anesthetizing and antiseptically treating or pretreating anatomic surfaces for invasive surgical or treatment procedures. In particular, compositions and methods according to the present invention are used to treat ocular surfaces for intravitreal injections and other ophthalmic procedures. Compositions of the present invention comprise antiseptic agents and anesthetic agents in an aqueous gel or semi-gel formulation base to provide for enhanced methods of treating anatomic surfaces such as the eye prior to surgical or other invasive procedures.

Description

RELATED APPLICATIONS [0001] This application claims the benefit of U.S. Provisional Patent Application No. 60 / 711,929, filed Aug. 26, 2005, which is herein incorporated by reference in its entirety.TECHNICAL FIELD [0002] This invention is related to compositions and methods for their use for treatment and pretreatment for procedures for medicine, surgery, and dentistry. In particular, the compositions and methods according to the present invention provide for the one-step preparation of a suitable antiseptic field in addition to achieving anesthesia for an anatomic surface as a treatment or as a pretreatment for medical or surgical procedures. BACKGROUND OF THE INVENTION [0003] Medical and surgical procedures often involve treating an anatomic surface to achieve antiseptic and anesthetic qualities, especially as a pre-treatment for an invasive procedure on or through that anatomic surface. To achieve appropriate antisepsis and anesthesia, antiseptic and anesthetic agents must be adm...
